BOILER. t 1

Application filed November To all whom it may concern:

Be it known that I, JOHN B. Sonnossnn, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new'and useful Improvements in a Boiler, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which like letters and numerals refer to like partsthroughout.

'This invention relates to means and apparatus for obtaining acontinuous and unifrom steam pressure where the working conditionssubmit the boiler to fluctuating loads.

The object of this invention is to provide a boiler or auxiliary theretofor retaining a portion of the energy when the load is light andimparting the energy when the boiler is called on for a sudden loaddemand.

The other object of this invention is to provide a boiler or auxiliarythereto to maintain a nearly uniform pressure.

In the drawings,

Fig. 1 is a longitudinal sectional view of a boiler drum showing theinvention applied,

Fig. 2 is a transverse sectional view of Fig. 1,

Fig. 3 is a perspective view of one of the containers used in theinvention.

Referring more to the drawings in detail 1 is a steam inlet pipeconnecting the manifold 2 which is provided with the distributing pipes3. 4 is the usual cylindrical drum being closed by the heads 5. Alongthe sides of the boiler is placed the containers 6, of which there is anumber of tiers extending the entire length of the drum 4 and thecontainers are super-imposed above each other with the longitudinalportion alternated in each tier. The bottom of the container 6 is formedexteriorly concave as at 7 to permit the tree circulation of water andsteam between the containers 6, after they are assembled in the drum asshown in the drawings.

The container 6 is filled with the metal 8 which is of low melting pointsuch as lead,

tin, bismuth, etc., 9 is the dome having the head 10 and the steamoutlet 11.

The drum 4:, shown in the drawings, is used for illustrating theapplication of the invention. This drum, however, may'comprise theordinary drum of tubular boilers. or the like, the drum being usedmerely to illustrate the application of the invention. From thedescription of the invention, it is apparent that the invention may beused in the water and steam containers of any make of boilers, the drumillustrated in the drawings forming no specific part of the invention.However, it it is desired touse a separate drum, it may be used and thesepa rate drum suitably connected by the pipe 1 to the boiler with whichused. If desired, the blocks may be positioned in the steam dome inwhich certain amount of condensation will take place. However, it is theintention to place the containers in the water contained within theboiler as this water will be raised to a sufliciently high temperatureto effect the purposes desired.

From the above description it will be apparent by connecting my devicein the steam line the steam can be regulated to the required temperatureand thus while the boiler is at light load the excess heat will melt themetal 8. A suitable composition tor the purpose would be an equal amountof lead and tin or a mixture of one-half parts of tin to one part oflead, so that the melting point would be low enough to permit the watercontained within the boiler to melt the metal which is placed within thereceptacle 6. It is apparent that there will be some condensation and acertain amount of water will reside in the easing now, therefore as theload is increased the metal 8 which has been heated, by its cooling willimpart its heat to the water 12, and generate addditional steam to takecare of the sudden loa I Thus having described my invention what I claimis new and desire to secure by Letters Patent is: e

1. A device of the'class described, adapted for positioning in areceptacle in c0111 munication with a boiler, and adapted for beingsurrounded by the water of the boiler, comprising a plurality ofseparate rectangularly shaped receptacles having eXt-eriorly concavebases, said receptacles being filled With a metal of a low meltingpoint.

2. A device of the class described comprising a plurality ofsuperimposed rectangularly-shaped receptacles, adapted for positioningin the water of a boiler, said receptacles being filled with a metal ofa melting point below the normal temperature of the water in said boilerwhen in operation.

In testimony whereof I hereunto aflix my signature. JOHN B. SCHLOS'SER.
